System

Abstract:

This system magnifies the electric power through the initial electric power received from a power supply such as Solar Panel, City Network, or lead acid battery. The device of the system consists of the following 3 parts. The first part represents the power source of the system that consists of a Solar Panel or city network to feed an electric charger and a chargeable lead acid battery. The second part consists of power switch, control board, capacitor, spark gap and primary coil. The third part, which consists of secondary coil, high voltage rectifier, and capacitor bank, feeds the high voltage step down transformer with a main volt oscillator to run the load. This system mainly depends on electromagnetic resonance theory that gives more output power than input by replicating the resonance process that needs a capacitor and a coil (LC circuit) in resonance condition.

System Description:

The system is feeding with power through solar panel or city network where user can select which input will be used through controlling the switchl .User also can select between manual and automatic feeding. In automatic mode system will monitor the availability of the solar panel and city network so it can decide which source will feed this system. In Manuel mode, system will use solar panel first then switch to city network after discharging battery power.

* Refer to Figure 2 Charger:

The system contains battery charger to achieve feeding power continuously to it. the charger is high performance and good stableness. This charger will support up to 12 volt and 12 amperes. Charger will be feuded with power through solar panel or city network and charge the lead acid battery smartly as it will stop charge the battery when it filled.

For Charger Circuit Diagram Refer to Drawing 3

Solar panel:

System uses one solar panel up to 256 watts. The most typical size used for residential installations is 65 inches by 39 inches. It will feed charger with necessary power to charge lead acid battery.

Lead acid battery:

It composes of a lead-dioxide cathode, a sponge metallic lead anode and sulphuric acid solution electrolyte. The cell voltage is 12 volt. This battery will feed the control board with essential operating power. The system is mounted by up to 12 volt and 12 ampere lead acid battery.

Switchl & Switch2:

System uses these switches to select between different input power sources. It controlled by the system control board.

For Switchl & Switch Circuit Diagram Refer to Figure 4 Control hoard; Description:

The whole system is mainly controlled by this board. It monitors the input power of the solar panel and city network also it measures the voltage level of the lead acid battery to decide which input source it will be feeding with. It contains a fly back transformer driver. User can set frequency which fed to this driver to obtain high voltage at a specific frequency to feed the resonant circuit. Also it controls the resonant tuning motor.

Refer to Figure 5 User interface:

It consists of LCD 4*20 &keypad 3*3 to allow users to input system parameters such as output power, input power, manual or automatic mode, operating frequency, display battery voltage level, device temperature and alarm messages.

Refer to Figure 13 Flvhaek transformer:

This transformer used to generate high voltage saw tooth signals at high frequency predefined by system user. It can generate up to 50 KV with frequency range from 15 KHZ to 1MHZ. The primary winding of the flyback transformer is driven by a MOSFET from a DC supply (lead acid battery) when the MOSFET is switched on the primary winding causes the current to build up in a ramp. When the MOSFET turned off, the current in the primary winding falls to zero then the energy stored in the ferried core is released to the secondary as the magnetic field in the core collapses. The secondary winding voltage rises very quickly.

Refer to Figure 17 Resonance Circuit:

The control board contains an oscillator driver to drive the flyback transformer, which together produce an Alternating Current of about 9,000 volts at a frequency of 35,100 Hz predefined by the system. System could lower the flyback output high volt as system gets great output power at lower inputvoltages.

The particular flyback driver circuit which control board is using here has two separate outputs out of phase with each other, so it connects together and uses a blocking diode in each line to prevent either of them affecting the other one. The high-voltage output line has a very small, encapsulated, spark gap in it and the line is also earthed. The device looks like this:

The output of the flyback transformer is used to drive the primary "LI" winding that is a Tesla Coil style transformer. The operating frequency is set and maintained by the flyback driver circuitry that contained in the control board. The resonant frequency of the LI coil and the capacitor across it to match the flyback driver circuit frequency. The frequency of the "LI" coil winding will induce exactly the same frequency in the "L2" secondary winding. The wire of the LI coil is usually much thicker than the wire of the L2 coil. System uses an acrylic transparent plastic tube as the former for the "LI" primary coil winding. The wire is fed into the former, leaving clearance to allow the former to slide all the way into the outer coil. The wire is fed up inside the pipe and out through another hole to allow the coil turns to be made on the outside of the pipe. Sliding is automatically controlled by a DC motor derived by the control board. This sliding operation allows the primary coil "LI" to be positioned at any point along the length of the "L2" secondary coil, and that has a tuning effect on the operation of the system. The positioning of the "LI" coil along the length of the "L2" coil, adjusts the voltage to current ratio produced by the coil. When the "LI" coil is near the middle of the "L2" coil, then the amplified voltage and amplified current are roughly the same. The exact wire ratio of these two coils gives them an almost automatic tuning with each other, and the exact resonance Between them can be achieved by the positioning of the "LI" coil along the length of the "L2" coil.

The length of wire in the "LI" coil turns is one quarter of the length of wire in the "L2" coil turns.

The output from the "L2" coil in order to get large amounts of conventional electrical power out of the device. System uses capacitors with voltage rating 8,000 or 9,000 volt and a large capacity and they are used to store the circuit power as DC prior to use in the output load. This is achieved by feeding the capacitor bank through a rated for both high voltage and high current diode so the device produces 8,000 volts at 20 amps, this rectifying diode has to be able to handle that level of power, both at start-up when the capacitor bank is fully discharged and "L2" is producing 8,000 volts, and when the full load of 20 amps is being drawn.

When the system is running, the storage capacitor bank behaves like an 8,000volt battery which never runs down and which can supply 20 amps of current for as long as you want. Then feed the power stored in the capacitor bank to high volt step down transformer with a main frequency oscillator to get a 220volt 50 Hz AC output.
